Her gross profit from the purchase and sale of armchair was what percentage greater than the gross profit of purchase and sale of coffee table?Stmt 1 - Martha paid 10 percent more for the armchair than for the coffee tableStmt 2 - Martha sold the armchair for 20 percent more than she sold the coffee table.

1. If n is a nonzero integer, 1^1, 1^(-1), (-1)^1, and (-1)^(-1) all are equal to 1. So z could be 1 or -1 as does n. NSF..2. If Z > 0, 1^1, 1^(-1), 2^0, or (11)^0 all ends in 1. So Z could be 1, 2, ................infinite. NSF..

From 1 and 2: Z and n must be 1. SUFF... Thats C.

In reference to the post above ....

i dont understand why the solution cannot be A.anything raised to 0 is 1, and 1 raised to any power is 1.stmt A says, N is not =0. hence Z has to be 1. so shouldn't A suffice?(i dont understand how there can be any value other than 1 for Z.)

what if we consider n as 2 and Z = -1 ? we get Z^n = (-1)^2 as 1 thereby we are getting multiple values of Z i.e both 1 and -1hope this helps
